Abstract:
We present new central stellar velocity dispersion measurements for
428 galaxies in the Palomar spectroscopic survey of bright, northern
galaxies. Of these, 142 have no previously published measurements,
most being relatively late-type systems with low velocity dispersions
(≲100km/s). We provide updates to a number of literature dispersions
with large uncertainties. Our measurements are based on a direct
pixel-fitting technique that can accommodate composite stellar
populations by calculating an optimal linear combination of input
stellar templates. The original Palomar survey data were taken under
conditions that are not ideally suited for deriving stellar velocity
dispersions for galaxies with a wide range of Hubble types. We
describe an effective strategy to circumvent this complication and
demonstrate that we can still obtain reliable velocity dispersions for
this sample of well-studied nearby galaxies.
Description:
A full description of the Palomar survey is given by Ho et al. (1995,
Cat. J/ApJS/98/477, 1997, Cat. J/ApJS/112/315). This survey covers
a nearly complete, magnitude-limited sample of 486 galaxies from the
Revised Shapley-Ames Catalog (Sandage & Tammann, 1981rsac.book.....S 1981rsac.book.....S,
Cat. VII/51) that satisfies BT≤12.5mag and δ>0°. The
spectra were acquired using the Double Spectrograph mounted at the
Cassegrain focus of the Hale 5m telescope at Palomar Observatory.

Note (2): Notes as follows:
1 = The adopted velocity dispersion was estimated from the [NII]6583Å
emission line following the procedure of Ho (2009ApJ...699..638H 2009ApJ...699..638H).
2 = Stellar features too weak in the blue or red.
3 = Spectrum partly corrupted.
4 = The HyperLeda value of σ=240km/s pertains to the
"southeast-northwest" component of this merging galaxy; the correct
dispersion for the primary nucleus is σ=100±25km/s
(see Section 3.4).
5 = Blue spectrum not available.
6 = Blue spectrum not well resolved.
7 = Red spectrum not well resolved.
8 = Blue fit unreliable.
9 = Red fit unreliable.
10 = G band corrupted in blue; masked out.
11 = The literature value corresponds to the central nuclear star cluster;
the Palomar value is more representative of the central 2"x4" region.
12 = Velocity dispersion possibly overestimated slightly.
